System Architecture Components

The mobile App that includes the Unzer mobile SDK. All security relevant payment information are directly send to the Unzer server in order to be secure and PCI complaint. The mobile SDK uses the Public Key provided by Unzer.

Merchant Server

Your server part that provides various services for your application and talks through the server side Unzer SDK with the Unzer backend. All charges and payment authorisations are triggered from the server by using the Private Key provided by Unzer.

Unzer server

The Unzer backend is responsible for fulfilling your charge and authorisation requests and talks directly to the various payment provider (credit card, …). You should always communicate through the our SDKs with our system.

Payment Provider

You don’t communicate directly with the Payment Provider. For some payment requests the Unzer SDK will require you to open a web view to show more details to your customer (e.g. Mastercard 3DS, Paypal, …).

Mobile SDK Functionality

  1. Secure Payment Information transfer
